The Selection of Propeller and Primary Engine Matching of A 30 GT Fishing Vessel (Case Study KM Inka Mina 759)

Abstract

Reducing fuel consumption and carbon emissions in the development of ship propulsion systems following the required Energy Efficiency Design Index (EEDI) has become a concern for the fishing industry as determined by the International Maritime Organization (IMO). This study analyzes the suitability of using a 30 GT fishing vessel propeller and propulsion engine for optimum efficiency. The analysis focuses on developing a propulsion system selection model, studying the characteristics of the ship's resistance, loading propellers, and selecting the appropriate engine. The propeller-engine matching procedure predicts the propeller and engine suitability. Furthermore, the Analytic Hierarchy Process (AHP) method determines the suitability level for the propeller and diesel engine. The results showed the highest level of suitability for the Yanmar 6CH-HHTEC engine versus the A.30X34 type propeller with 31.7%. Then the Deutz BF06M1013MC engine versus the B.30X28 propeller type, the Yuchai YC6A170C engine versus the B30X28 propeller type, and the Volvo D7ATA engine versus the B30X28 propeller type with percentages of 26.6%, 26.4%, and 15.3%, respectively. The high level of SP2 selection is due to the propulsion system having minimal noise levels, dimensions, and engine weight but having maximum power.

“…Nevertheless, this study was preliminary for a combination of ESD such as PBCF or nozzles. Future work of optimization needs to carry out using a sophisticated method such Analytic Hierarchy Process (AHP) [9].…”
